Double-sleeper tamping device

Abstract

The invention discloses a station track double-sleeper tamping device, which comprises a box body, a vibration shaft, an inner clamping oil cylinder, an outer clamping oil cylinder, an inner pickaxe arm, an outer pickaxe arm, an inner tamping pickaxe, an outer tamping pickaxe, an air cylinder, stop blocks, a guide post, an outer support arm, an oil tank assembly and an inner support arm, wherein the box body is at least formed by a middle body, a cross beam, an end plate, an inner support lug boss, an outer support lug boss and a stop baffle plate through welding, the distance from the center of a pin hole of the outer pickaxe arm arranged on the cross beam of the box body to the center line of the box body equals 600mm+/-20mm, the outer support arm and the oil tank assembly comprise an outer support arm, two oil tanks and a flywheel cover, the inner support arm comprises an inner support arm body and a flywheel cover, the stop blocks are arranged between the front end of a piston rod of the outer clamping oil cylinder and the cylinder cover of the oil cylinder, the stop blocks comprise a fixed stop block and a turnable stop block, through using different numbers of stop blocks, the downward inserting positions and clamping strokes of the outer side stamping pickaxe are regulated, and the operation requirements of different sleeper spaces are met. The station track double-sleeper tamping device has the advantages that the structure is reasonable, the station track operation is met, and the main track operation is also met.

Description

[0001] technical field [0002] The invention relates to a railway road maintenance mechanical tamping vehicle, in particular to the structure of a tamping device. Background technique [0003] The tamping device is the main working device of the large-scale road maintenance machinery tamping vehicle. It is mainly used for tamping the ballast on both sides of the rail to improve the compactness of the ballast on the bottom of the pillow, and cooperates with the lifting device to eliminate the unevenness of the track and enhance the stability of the track. [0004] At present, the DC-32 and DCL-32 double-sleeper tamping vehicles widely used on my country's lines are mainly used for tamping operations on the main railway line, while the station line lines within the scope of railway stations have been ignored by people, and even some station lines It has been in disrepair for a long time and has become a bottleneck in the development of railway transportation. Therefore, it i...
